The Lowdown

Alright, my friends, Rusty here. Gotta be honest with you, the next couple of weeks are a real mixed bag. We’ve got a long, slow spell of small waves, and then one big, powerful pulse that’s gonna have the heart pumping. But you’re gonna have to be patient. Real patient.

We’re talking about Jaconé. Water’s at 23°, which is right where it should be for this time of year. Nothin’ weird happening there.

The start of this run is weak. Monday the 17th is a write-off – poor conditions, small and messy. Tuesday the 18th has a tiny clean window in the morning, but the swell is weak, short-period junk. Not worth getting wet for, really. Wednesday and Thursday are more of the same – small, short-period waves, nothing with any grunt. We’re just waitin’, prayin’ for a pulse.

Then Friday the 21st, we get a little teaser. The morning shows a 2.0m easterly swell with a clean offshore breeze, and the energy is picking up – a moderate 619 units. It’s a small bump, but it’s there. But, just as quick, it backs off. The weekend looks a bit jumbled. Saturday’s poor with onshore winds, and the extra southwest swell that shows up in the afternoon is just messy. Sunday is calm and glassy, with a clean 1.4m south-southwest swell – surfable, that’s about it. Nothing to get too excited about.

Now, Monday the 24th, things start to move. That south-southwest swell starts to build, hitting 2.3m with a solid 1370 units of energy behind it. But the wind turns cross-onshore, putting a bit of chop on it. It’s marginal, ya gotta be picky.

But Tuesday the 25th is the big one. The overnight build brings in a solid 3.0m swell from the south with a long 15-second period. That’s real groundswell, loads of energy – 3294 units. But, and this is a big “but”, that size is just too much for Jaconé. The models are saying it’s just too big for the break. The morning is gonna be a washing machine, likely closeouts everywhere, especially with that long period. If you paddle out, you’re a braver soul than I.

The window you want is Tuesday afternoon. The swell backs off slightly to a still-serious 2.5m, also from the south-southwest with a long period. The wind swings around to a cross-offshore angle, cleaning it all up. This is the standout of the whole forecast. It’s gonna be big, powerful, and perfect for experienced surfers. This is a day for the crew who can handle heavy, unforgiving waves. If you’re just starting out, give it a wide berth.

Wednesday the 26th is the follow-up act, and it’s still a solid day. The swell is down to 1.9m from the south with a lighter offshore wind in the morning. The energy is still strong at 1263 units. This is a great option for someone who found Tuesday a bit too full-on. After that, it’s a slow fade. Thursday is smaller and glassy in the morning, a nice, clean day. From Friday the 28th onwards, the swell just drops away and we’re back to the ordinary stuff. A few clean, small windows here and there, but nothing that’s going to get you out of bed early.

So there you have it. One day of proper, heavy, world-class surf around the 25th, and a whole lot of small stuff surrounding it. Keep an eye on that forecast, it’s the one that matters.

Rusty, out.

Information about the Jaconé Surf forecast

The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.

Jacone is 14 km (9 miles) from the city of Saquarema. If you plan a holiday in Rio de Janeiro, look for hotels and other accommodation in Saquarema. Saquarema has rooms for a wide range of budgets as well as car hire and transport links.
